BODY-BOLSTER.

ooneea.

To all whom it may concern:

Be it known that we, ROBERT E. FRAME and JOHN M. ROHLFING, residing atSt. Louis, Missouri, and being citizens of the United States, haveinvented certain new and useful Improvements in Body-Bolsters, of whichthe following is a full, clear, and exact description, such as willenable others skilled in the art to which it appertains to make and touse the same, reference being had to the accompanying drawings, whichillustrate the preferred form of the invention, though it is to beunderstood that the invention is not limited to the eXact details ofconstruction shown and described, as it is obvious that variousmodifications thereof will occur to persons skilled in the art.

In said drawings: Figure 1 is a plan view of improved bolster. Fig. 2 isan elevational View thereof. Fig. 3 is a transverse sectional view, thesection being taken central of the center bearing on line 3-3 of Fig. 1.Fig. 4 is an end elevational view. Fig. 5 is a vertical sectional view,the section being taken on line 5-5 of Fig. 2. Fig. 6 is a diagrammaticelevational view showing the girder from which the bolster isconstructed in full and dotted lines indicating its original shape andthe lines along which it is cut through its web portion.

The object of the invention is to provide a simple, strong and durablebody bolster formed of a single l-l section of rolled metal, which is ofless depth near its end portions than near the middle and is reinforcedin such a manner as to best serve the purposes for which it is intended.

Referring to the parts, 1 is the upper flange which is continuous fromend to end and is connected throughout its length with the web 2. 3indicates the part of the lower flanges which is left integral with saidweb 2.

4-4 indicate the end portions of the lower flanges which are severedfrom the web 2 and from the portions 5 of said web which are cut out andremoved from the girder.

6 indicates a Vertical opening extending from top to bottom through thegirder, as shown in dottedlines in Fig. 6.

After the portions 5 of the web are out out, leaving the two flanges 4at each end severed from said portions 5, the said flanges 4 arebentupwardly to the position shown 5 in Fig. 2 and as indicated insection in Fig.

- Specification of Letters Patent.

Serial No. 502,367.

5. The bottom flange 4, may be bifurcated longitudinally in alinementwith the web 2, so that when the flanges 4, are bent upwardly as shownin Fig. 2, they will rest at each side of the web as in Fig. 5, ifdesired, although the portion 5, may be cut out without bifurcating thebottom flange 4. The pin socket members 7, which may be either pressingsor castings, are placed in position and riveted to the top flanges 1 andto the web portions 2, as best shown in Fig. 2. Said pin socket membersare preferably castings which are provided with reinforcing ribs 8extending downwardly approximately the depth of said member 7 and saidsocket members 7 rest upon the upper edges of longitudinally disposedangles 9, which extend at each side of the web 2 substantially thelength of the bolster and are riveted to said web and to the lowerflanges 3-4 throughout their length, some of the rivets connecting theseangles 9 with said lower flanges 3 extending through the laterallyprojecting flanges 10 of the center bearing 11, thereby securing saidcenter bearing in position, as best shown in Fig. 2.

For convenience of manipulation the ver tical legs 9 of the angles 9 arecut away slightly at their ends to provide suflicient clearance betweensaid angles and the horizontally extending flanges 1 of the bolster.Side bearings 12 are provided for well understood purposes.

.What we claim is:

1. In a bolster a rolled member provided with integral top flange andbifurcated lower flange.

2. A bolster comprising a rolled member provided with a continuous topflange and a bifurcated bottom flange.

3. In a bolster, the combination comprising a rolled member havingintegral upper flanges and web portion, a bottom flange bifurcated atits end portions and continuous angles connected with said bottom flangeand the web portion.

4. In a bolster, the combination comprising a flanged girder member ofrolled metal, parts of the flanges of which are cut from its 1web andsubsequently connected therewit 1.

5. In a bolster, the combination comprising a flanged girder member ofrolled metal with bifurcated flange and means connecting said bifurcatedportion with the web.

6. In a bolster, the combination comprising a flanged girder member ofrolled metal having one of its flanges bifurcated from the endsinwardly, in combination w th reinforcing means connecting saidbifurcated flange to the web.

8. In a bolster, the combination comprising a flanged girder member ofrolled metal having one of its flanges bifurcated from the endsinwardly, in combination with angles connected with the web and saidbifurcated flange.

9. In a bolster, the combination comprising a flanged girder member ofrolled metal having one of its flanges bifurcated from the endsinwardly, in combination with longitudinally extending angles above saidbifurcated flange forming a pin seat.

10. In a bolster, the combination comprising a flanged girder member ofrolled metal having one of its flanges bifurcated from the endsinwardly, in combination with longitudinally disposed strengtheningmeans connecting said bifurcated flange with the web, and a centerbearing secured to a flange of said girder and to said angles.

11. In a bolster, the combination with a rolled and flanged girdermember, parts of whose lower flanges are cut from the web thereof, ofmeans for attaching said flanges to the web and a center bearingconnected with the uncut portion of said flanges.

12. In a bolster, the combination with a rolled and flanged girdermember having integral upper flanges, a depending web and integral lowerflanges near its middle portion, of flanges severed from said web andrejoined near its end portions.

13. In a bolster, the combination with a rolled and flanged girdermember having integral upper flanges, a depending web and integral lowerflanges near its middle portion, of flanges severed from said web andrejoined near its end portions and a center bearing member connectedwith the integral lower flanges.
